Why retailers stock it

When climbing into a litter box hurts, a cat may start going beside it instead. This box has a low entry point designed so senior and arthritic cats can get in and out easily, and 9-inch walls that help keep urine and litter inside.

In September 2026, Google Keyword Planner showed about 12,100 US searches a month for a litter box for large cats and 2,900 for a senior cat litter box. This box has sold on Chewy.com since 2022 and had more than 100 five-star reviews there as of late 2025. It sits between basic plastic pans and electronic systems that cost hundreds of dollars.

  • Owners of senior and arthritic cats
